TYPEWRITING-MACHINE.

Application filed June 15,

writing-Machines, of which the following is a specification.

This invention relates to mechanism for controlling condensed record sheets in typewriting'machines, one. of the main features of the invention being the provision of'novel means forsecuring a forward shifting or advance ofv the record sheet after the com pletion of .the typing of a bill or item, thereby securing a suitable blank space between the records on thebills or the like.

Whilethe devices for advancing the record sheet may be used in various kinds of machines, they are herein shown in connection with a fan-fold machine of the type shown in the W ernery & Smith Patent No. 1,132,055, datedMarch 16., 1915, in which superposed plies of web are fed around the revoluble platen of an Underwood typewriting machine, sheets of carbon being in- .terleaved with the superposed plies, and the whole forming a unit which loops around the platen, the platen being displaceable upwardly for the purpose of permitting the loop to be straightened or. opened out, whereupon the carbons are'released and hence may be drawn backwardly to face fresh portions of the webs.

In such machines, after each form is filled up by using the typewriter, it is torn off from the web; but the condensed record sheet remains in the machine, not being torn off, and this enables copies of several forms to be accumulated upon one condensed record, which is usually not a web but in the. form of a separatesheet,interposed between the webs and the platen, to form part of the unit.

One of the features of the present improvements consists in the provision of means for advancing the record sheet independently; and this advancing means is preferably connected to the means whereby a release is effected between the platen'and the usual feed-rolls that run thereon, for relieving all the work from the control of said rolls. In the presentinstance, such roll-release is effected by a lifting of the platen, whereby the sheets are liberated, and

therefore to theplaten-lifting means I connect a device for advancing the condensed record sheet; although the invention is-not llmlted in all cases to the specific roll-releasing means.

In the specific form of my invention herein illustrated, I provide upon the delivery s de of the platen apair of feed-rolls or devlces between which-the leading-end of the condensed record sheet is introduced. These rolls, however, are normally separated so the condensed record sheet, but when the re lease 1s effected between the platen and the 'bottom' feed-rolls, these special feed-rolls are preferably effected by means of a pinion which is fixed upon the shaft of the upper of the two new feed-rolls, which pinion meshes with a'station'ary segment, which is concentric with the hinge upon which the platen frame swings upwardly at the platen-displacing operation; This upward movement of the platen is therefore accompanied by a positive rotation of one of the special feedrolls, whereby the condensed record sheet is advanced by co-action with the opposed new feed-roll. This advances the record sheet preferably to the extent of about three linespaces.

Two line-spaces are sufficient for spacing apart the successive entries or groups upon thecondensed record sheet; but an additional advance is preferably made, in order to compensate for the downward drag or retraction of the condensed record sheet, which is apt to occur at the subsequent dropping of the platen back to normal position. The invention may be used either for comrecord sheet, or for the purpose of securing the desired blank space between entries upon the record sheet, or for both cases, as in the present form of the invention.

At the initialpart of the return movement of the platen from its elevated position, a separation is automatically effected between the special feed-rolls, so that they may not have any tendency to feed the condensed 110 that they can do nothing more than guide record sheet backwardly while the platen is being returnedto normal printing posi-- tion c During such drop of the platen, the

. upper of the two special feed rolls may revolve idly; while the lower of said rolls, being'out of contact does notrevolve, but remains in position to be thrown into co-ac- .tion' with the upper roll at the initial part of the succeeding rise of the platen as afore- .Thus, the condensed record said. 4

sheet may be fed forward line by lineby the usual linespacing mechanism, together with the plies 'of web, whether the same be fan-fold or separate plies, and said condensed record sheet will be automatically spaced between entries or groups thereon, and, in addition,

' if desired-the backward drag of the condjensed' recordsheet, if it occurs, may be compensated 'for,

Other features and advantages will hereinafter appear. I 4

in fan-fold form or separate plies, are led" The plies of web 10, which may be either into the machine in the usual manner, and passed. forwardly and then downwardly under and around the platen 11 and up in front thereof; the feed-rolls 12, Fig. 2, pressing the work against the platen; said feed-rolls being preferably releasable by means of a finger-piece 13 in the usual manner. In rear of the platen is mounted .a carbon carrier 17, Figs. 1 and 2, which is movable backwardly and forwardly upon tracks 1.8 provided upon the typewriter car riage l9, carbons 20 being connectedto blades 21 which are fixed upon said carrier,

the blades and carbons alternating with the plies of Web, and the rotation of the platen -at the line-feeding operations pulling forward not only the web, but also the carbon sheets, together with the carbon carrier.

Aconden'sedrecord sheet 25 is placed between the webs and'the platen in superposed relationwith the webs, and is faced by the uppermost carbon of, the carbon carrier and drawn forwardly and back with said carbon carrier.

The leading endof said condensed record sheet is introduced between a pair of auxiliary feed-rolls 26, 27, which may be arranged at the delivery side of the platen; these rolls, however, be-

ing normally separated, as at Fig.2, and normally ineffective during the line-feeding operations of the platen, so that the condensed record sheet advances idly between said rolls.

' When the platen is lifted with its swing frame 28, Figs. 3 and 4, (comprising arms 29 and a rock shaft or hinge 30, the latter journaled upon the typewriter carriage), to

permit the loop of webs and record sheet to be straightened or opened out so that the carbons can be drawn back to face fresh portions of the webs, said rolls 26, 27 are' brought together automatically and proceed to rotate, thereby advancing the record sheet 25' independently of the remaining work-sheets or webs 10.

The rolls 26, 27, may be brought together automatically in any desired way, for example, by mounting the under roll 27 upon -a rms33 connected by a rock shaft 34, and

providing upon said rock shaft a controlling arm 35, Which is held in either roll-opening or roll-closing .position, by

means ofa detent 37, which may, for example, be in the form of a V-spring to enter either of two notches 38, 39, provided upon-said arm .35. Upon said arm is carried a pin or roller 40, in the path of which is a member in the form of an abutment or cam 41, so that as the platen swing I frame 28 rises, said cam 41 intercepts said pin 40 and causes'the roll-carrying arm 35 and rock shaft 34 to rotate and the spring 37 to enter the other-notch 38 in the arm 35, whereby the under feed-roll 27, Fig. 3, is

caused to press the condensed record sheet 25 against the upper feed-roll 26 and hold it there. In the further displacement of the platen frame upwardly, the pin 40, Fig. 3, escapes from the cam 41 while the spring 37 maintains the arm 35 and roll 40 in the new .positions.

During thisupward displacement of the platen swing frame, a pinion or segment 42 -upon a shaft 43 of the upper of the two condensed record feed-rolls 26,- by reason of its engagement with a fixedpinion 44 which is concentric with thes'haft or hinge 30 of the platen swing frame-28, is caused to rotate, thereby advancing the condensed record sheet 25 in line-feeding direction. The. extent of this advance will depend upon "the extent of movement of the platen swing feed-rolls 27 will be released at the initial movement of the roller 47 thereover until said roller is in a position directly in front of the abutting end of said cam, as in F 1g. 4.

In this posltion of the platen frame, the webs 10 may be. adjusted and the carbons retracted while the record sheet is held by the auxiliary feed-rolls 26, 27 against accidental displacement. I

During the early portion of the return movement of the platen,'the second pin 47 upon said roll-carrying arm 35, Fig. 5, engages the abutment or cam-48 whlch is 111 the path thereof, and thereby forces said arm to return to its normal position with the V-spring 37 in the other notch 39 and the lower feed-roll 27 separated from the upper feed-roll 26; said pin 47 then escaping passes said abutment 48, not meeting with further interference during the remainder of the return movement of the platen down to normal position. Hence,

the principal portion of the rotation of the roll pinion 42 during the return movement of the platen is idle,since the rolls .26,

27 are separated, and the condensed record sheet 25 is therefore not drawn back by said 'rolls. If said record sheet is retracted slightly by reason of the depression of the. platen, thls will be a matter of no moment,

since the original advance of said record sheet effected as aforesaid by its-rolls, will be much greater than the incidental retraction or dragging back of the record sheet during the downward return of the platen I aforesaid.

To set the auxiliary feed-roll controlling mechanism into position for. a succeeding platen-displacing operation, the first pin or roller 40, which has previously co-acted with the cam 41 for moving the feed-rolls 26, 27 into effective over said cam 41 until the roller 40 is moved in front of the abutting end of said cam 41, in which position said cam will be effective to swing vthe arm 35 when the platen is lifted. To permit said first pin or roller to thus move over the cam 41, said cam is also provided with'a pivot 49 and supported by a spring 50 in a manner similar to the forward cam' 48.

From the foregoing, it will be understood that the record sheet 25 will be line-fed together with the plies of web 10 and that it will also receive an extra advance movement independently ofsaid plies, so that it is not necessary for the operator to bear in position, rides back idly= and preferably at the beginning of the return-stroke of the platen.

Variations may be resorted to Within the scope of the invention, and portions of the im rovements may be used without others. aving thus described my invention. '1 claim:
